Botanical Name : Rhododendron ‘PJM’
Family: Ericaceae
Subfamily:Ericoideae
Tribe: Rhodoreae
Genus: Rhododendron
Kingdom:Plantae
Order: Ericales

Common Name: Rhododendron

Habitat : Rhododendron ‘PJM’  is  mostly  grown in the midwestern countries.  A hybrid of garden origin, R. minus x R. dauricum

Description:
Rhododendron ‘PJM’ is an evergreen broadleaf evergreen Shrub growing to 3 m (9ft 10in). Leaves are elliptic, flat to convex, obtuse apex, cuneate base, rust colored scaly indumentum, deep mahogany-purple November to April. Upright, dense growth habit. Flowers are openly funnel-shaped, wavy edges, 1½” across, lilac purple to light violet. Several clones are known as well as a number of forms.The flowers are hermaphrodite (have both male and female organs) and are pollinated by Insects..CLICK & SEE THE PICTURES:

Cultivation:
Succeeds in most humus-rich lime-free soils except those of a dry arid nature or those that are heavy or clayey. Prefers a peaty or well-drained sandy loam. Succeeds in sun or shade, the warmer the climate the more shade a plant requires[200]. A pH between 4.5 and 5.5 is ideal. This is an exceptionally hardy cultivar. Succeeds in a woodland though, because of its surface-rooting habit, it does not compete well with surface-rooting trees. Plants need to be kept well weeded, they dislike other plants growing over or into their root system, in particular they grow badly with ground cover plants, herbaceous plants and heathers. Plants form a root ball and are very tolerant of being transplanted, even when quite large, so long as the root ball is kept intact. Plants in this genus are notably susceptible to honey fungus.
Propagation:
Seed – best sown in a greenhouse as soon as it is ripe in the autumn and given artificial light. Alternatively sow the seed in a lightly shaded part of the warm greenhouse in late winter or in a cold greenhouse in April. Surface-sow the seed and do not allow the compost to become dry. When they are large enough to handle, prick out the seedlings into individual pots and grow them on in a lightly shaded position in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Layering in late July. Takes 15 – 24 months. Cuttings of half-ripe wood, August in a frame. Difficult.

Medicinal Uses: Not yet known.
Other Uses: Plants can be grown as a hedge. It is also grown in the garden for it’s good looking flowers.

Known Hazards: Although no specific mention of toxicity has been seen for this species, it belongs to a genus where many members have poisonous leaves. The pollen of many if not all species of rhododendrons is also probably toxic, being said to cause intoxication when eaten in large quantities.

Gypsophila struthium

[amazon_link asins=’B072M75LQW,B00Y0GEKQK,B072KYW783,B00R33G3RQ,B0739ZH872,B0013A2HA2,B0077TBPCE,B00G9GX4E8,B01KL7R900′ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’99abb3ff-7bf5-11e7-ac0d-4f303faf8f15′][amazon_link asins=’B06Y4QF27M’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’7279370e-7bf5-11e7-b601-5d3840a1f4ef’]

 

Botanical Name: Gypsophila struthium
Family: Caryophyllaceae
Genus: Gypsophila
Kingdom: Plantae
Order: Caryophyllales

Common Name: Egyptian  Soapwort,  Baby’s-breath

Habitat : Gypsophila struthium is native to Eurasia, Africa, Australia, and the Pacific Islands.

Description:, 
Gypsophila struthium is a perennial herbaceous plant with a stem 1 to 2 feet in height.The leaves are variable in shape. The inflorescence is usually a cyme or a thyrse, branching intricately. Each small flower has a cup-like calyx of white-edged green sepals containing five petals in shades of white or pink. The fruit is a rounded or oval capsule opening at valves. It contains several brown or black seeds which are often shaped like a kidney or a snail shell.

CLICK & SEE THE PICTURES : 

The root is generally in lengths of 4 to 6 inches, 1/2 to 1 1/2 inches in diameter; colour a yellowish white, furrowed down its length externally with lighter places where the cortex has been rubbed. The section is of a radiate and concentric structure. Taste bitter, then acrid; odour slight; powder irritating to the nostrils. This variety is rarely used medicinally, the Soapwort (Saponaria officinalis) being used as a substitute. The flowers are hermaphrodite (have both male and female organs)
Cultivation :
Requires a sunny position and a deep soil. Lime tolerant. Grows well in a dryish soil.
Propagation :
Seed – we have no information for this species but suggest sowing the seed in a greenhouse in spring. When they are large enough to handle, prick the seedlings out into individual pots and, if growth is sufficient, plant them out into their permanent positions in the summer. If the plants are too small to plant out, grow them on in the greenhouse for their first winter and then plant them out in late spring or early summer. Division in spring or autumn. Larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the spring. Basal cuttings before the plant flowers. Harvest the shoots when they are about 10cm long with plenty of underground stem. Pot them up into individual pots and keep them in light shade in a cold frame or greenhouse until they are rooting well. Plant them out in the summer. Root cuttings.
Medicinal Uses:
Alterative; Diaphoretic; Purgative; Skin; Tonic.

Tonic, diaphoretic, alterative. A valuable remedy in the treatment of syphilitic, scrofulous and cutaneous diseases, also in jaundice, liver affections, rheumatism and gonorrhoea, the decoction is generally used. Saponin is produced from this plant. Although rarely used, this species can be employed in many of the same ways as soapwort, Saponaria officinalis. It is a valuable remedy, used as an external wash, for the treatment of many skin diseases.

Other Uses : The plant contains saponins. This may be used as soap substitute.

Known Hazards: Although no mention has been seen for this species, at least one member of this genus has a root that is rich in saponins. Although toxic, these substances are very poorly absorbed by the body and so tend to pass through without causing harm. They are also broken down by heat so a long slow baking can destroy them. Saponins are found in many plants, including several that are often used for food, such as certain beans. It is advisable not to eat large quantities of food that contain saponins. Saponins are much more toxic to some creatures, such as fish, and hunting tribes have traditionally put large quantities of them in streams, lakes etc in order to stupefy or kill the fish.
